Use this command to specify the number of Shortest Path First (SPF) LSA thresholds to optimize the performance of the routing calculation.
| num-start | Specifies the number of LSA updates that force a full routing calculation. Valid values: 0 - 4294967295; Default: 4294967295. |
| num-restart | Specifies the number of LSA updates that interrupt and restart a full routing calculation. Valid values: 0 - 4294967295; Default: 4294967295. |
| num-ia-ext-full | Specifies the number of LSA inter-area/external updates that force a full routing calculation. Valid values: 0 - 4294967295; Default: 50. |
| num-intra-full | Specifies the number of intra updates that force a full routing calculation. Valid values: 0 - 4294967295; Default: 0. |
None.
OSPF router configuration.
The “no” form of this command restores the default values.
A value of 0 for either the number of LSA inter-area/external updates or intra updates means a full routing calculation would always be done for any inter-area/external update received.
This example shows how to change the number of LSA inter-area/external updates that force a full routing calculation to 75 leaving the remaining defaults unchanged:
System(rw-config)->router ospf 1 System(rw-config-ospf-1)->spf lsa-thresholds 4294967295 4294967295 75 0 System(rw-config-ospf-1)->
